Important thing is to note that a final variable doesnot need to be initialized at the time of decleration, but must be initialized before using it. BEFORE INITIALIZATION VAR IS CALLED Blank final var. You can use (invoke) a method to initialize it.

in continuation to the previous reply the blank final variable neednt be initialized at the place where it is declared. it must be initialized in all the constructors for that class.
Hope this helps
